Connectors and car adapter included The inner build quality is questionable It is by far the most functional power supply I have seen: 220 V and 12 V in (car adapter included), 12-22V out (with memory), USB 5 V out. However, the unit gave up in 5 minutes with an audible fizzling after connecting to a small laptop. I disassembled to see inside which looks quite messy. Provided that it doesn't fail, it is the most functional power supply for this money. Read more

It might be better regulated if loaded but I did not have the possibility to measure that. * You can change the voltage only in the first one or two minutes after power-up. I do not know if this is a faulty behavior or a safety feature. * I did not disassemble this but it seems like the voltage indicator is NOT and LCD but 7-segment LED display. Which is equally good, just not like advertised. Pretty good power supply still, hope it will do the job well. Read more

- Excellent build quality.

- Remember the last voltage selection - no need to reselect it after reapplying power (it was critical for me).
- Additional usb power outlet.
- Good choice of connectors. - Rather heavy.
- Slight delay (~0.5s) after powering the device before power appears on the outlet. I use it not for laptop, but to power up my DIY device. I need silent 12V 75W power adapter, and it do what it suppose to do. Good product. Read more
